Question

Y=_2×_4
F(0)=_2×0_4=
F(1)=_2×1_4=
F(2)=_2×2_4=
F(3)=_2×3_4=
F(4)=_2×4_4=
F(5)=_2×5_4=

Answer 1

Y=_2×_4

y = - 2x - 4   mesmo que
f(x) = - 2x - 4

x = 0
f(0) = - 2(0) - 4
f(0) = - 0 - 4
f(0) = - 4

x = 1
f(1) = - 2(1) - 4
f(1) = - 2 - 4
f(1) = - 6

x =2
f(2) = - 2(2) - 4
f(2) = - 4 - 4
f(-2) = - 8

x = 3
f(3) = -2(3) - 4
f(3) = - 6 - 4
f(3) = - 10
 
x = 4
f(4) = - 2(4) - 4
f(4) = - 8 - 4
f(4) = - 12

x = 5
f(5) = - 2(5) - 4
f(5) = - 10 - 4
f(5) = - 14
